Audi Q7 gets extensive changes. The previous V6 and V8 engines have been replaced with supercharged 3.0-liter V6s known as the 3.0T and 3.0T S Line, respectively. An eight-speed automatic is now standard on all Q7s, including the diesel-powered TDI model. The option for second-row captain's chairs has been deleted, while the Premium Plus and Prestige trim levels receive additional feature content.
